[0017] Figure 1This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the pad angle adjustment mechanism of this utility model.

[0018] As attached Figure 1 As shown, a control system-driven electric medical bed includes a bed frame 1, guardrails 2, an upper body pad 3, a lower body pad 4, and casters 5. Guardrails 2 are provided on both the left and right sides of the bed frame 1. An upper body pad 3 and a lower body pad 4 are provided on the bed frame 1. A width adjustment mechanism 6 is installed on the bed frame 1 to adjust the distance between two guardrails 2 on the same side. Two guardrails 2 are installed on each of the left and right sides of the bed frame 1. Four vertical swing mechanisms 7 for the guardrails are installed on the width adjustment mechanism 6. The output shafts of the four vertical swing mechanisms 7 are respectively connected to the four guardrails 2. The bed frame 1 is equipped with a pad angle adjustment mechanism 8, which is connected to the upper body pad 3. The head end of the bed frame 1 is equipped with a horizontal movement mechanism 10, which is connected to a height adjustment mechanism 9. The height adjustment mechanism 9 is equipped with a medicine bag hook 12. The bed frame 1 is fixed on the rotating part of the horizontal adjustment mechanism 11. The bottom of the horizontal adjustment mechanism 11 is equipped with casters 5. The width adjustment mechanism 6, the guardrail vertical plane swing mechanism 7, the pad angle adjustment mechanism 8, and the horizontal adjustment mechanism 11 are all electrically connected to the PLC.

[0019] The width adjustment mechanism 6 includes a motor 61, a screw 62 with positive and negative threads, a nut 63, and a sliding plate 64. The screw 62 with positive and negative threads is rotatably connected to the bottom of the bed frame 1. The body of the motor 61 is fixed to the bottom of the bed frame 1. The output shaft of the motor 61 is connected to the screw 62 with positive and negative threads. Nuts 63 are threaded onto both the positive and negative threads of the screw 62. The two nuts 63 are fixed onto the two sliding plates 64 respectively. The two sliding plates are slidably connected to the bottom of the bed frame 1. Two guardrails 2 are fixed on each sliding plate 64. The bed frame 1 is located between the two guardrails 2 fixed on the sliding plate 64.

[0020] The output shaft of motor 61 drives the positive and negative threaded screw 62 to rotate, thereby driving the two nuts 63 to move in opposite directions or relative to each other along the positive and negative threaded screw 62, thus causing the four guardrails 2 on both sides of the bed frame 1 to move in opposite directions or relative to each other. When the guardrails 2 are to be used, the two guardrails 2 at the front end and the two guardrails 2 at the rear end of the bed frame 1 are moved relative to each other by the width adjustment mechanism 6 until the two guardrails 2 on the same side are close together. When the guardrails 2 are to be lowered, the width adjustment mechanism 6 moves the guardrails 2 at both ends of the bed frame 1 outwards to the front and rear ends of the bed frame 1 respectively, and then the guardrail vertical plane swing mechanism 7 drives the guardrails 2 to swing downwards, thereby causing the left and right sides of the bed frame 1 to be freed from the obstruction of the guardrails 2.

[0021] The vertical swing mechanism 7 of the guardrail is a dual-head motor, and the output shafts of the dual-head motors are respectively connected to the guardrails 2 on the left and right sides.

[0022] As attached Figure 2As shown, the pad angle adjustment mechanism 8 includes a motor 81 and a connecting bracket 82. The body of the motor 81 is fixed on the bed frame 1. The end of the connecting bracket 82 is provided with a shaft. The connecting bracket 82 is hinged to the bed frame 1 through the shaft. The output shaft of the motor 81 is fixed on the shaft of the connecting bracket 82. The frame of the connecting bracket 82 is fixed to the bottom of the upper pad 3.

[0023] The rotation of the output shaft of motor 81 can drive the upper body pad 3 to swing in the vertical plane through the connecting bracket 82, thereby helping the patient to lift their upper body.

[0024] The horizontal adjustment mechanism 11 is an electric turntable. The electric turntable can drive the bed frame 1 to rotate in the horizontal plane, thereby adjusting the horizontal orientation of the bed frame 1.

[0025] The height adjustment mechanism 9 includes a straight tube 91, a screw 92, and a locking nut 93. The tail end of the screw 92 is provided with a slider, which is slidably connected inside the straight tube 91. The screw 92 is threadedly connected with the locking nut 93, and the top end of the screw 92 is provided with a medicine bag hook 12.

[0026] Rotating the locking nut 93 causes the screw 92 to move linearly up and down along the locking nut 93 and the straight tube 91, thereby adjusting the height of the medicine bag hook 12. The horizontal moving mechanism 10 can drive the medicine bag hook 12 to move horizontally and linearly at the head of the bed.

[0027] Locking nut 93 is a handle nut.

[0028] The PLC is equipped with a Bluetooth module. The Bluetooth module works with a Bluetooth transmitter to enable remote control operation.
